Which IP address range is considered private for IPv4?

The correct choice identifies the IP address range of 10.0.0.0 to 10.255.255.255 as a private range for IPv4 addresses. The Internet Engineering Task Force (IETF) has designated specific ranges of IP addresses as "private" in RFC 1918, which are meant for use within private networks and are not routable on the internet. The 10.0.0.0/8 range is one of those designated private ranges, providing a large number of available addresses for internal use, which is especially beneficial for organizations managing extensive networks.

Private IP addresses are significant in network design, as they offer various advantages, such as more efficient use of IP address space and enhanced security through isolation from the public internet. The other ranges indicated in the choices may overlap with public addresses or are not categorized as private. This distinction is crucial for anyone involved in networking and cybersecurity, particularly when configuring networks or understanding traffic flow and access controls.
